[Boost-users] [serialization] Error serializing std::wstring to text_oarchive on VC++

The fill method on mb_from_wchar calls std::wctomb, which is backed by 
'WideCharToMultiByte'.  This function uses the codepage defined in the 
current locale, however, the utf-8 codepage does not function properly 
on VC++ 7 or 8.  Would it be difficult to have the conversion use the 
code_cvt facet defined for the stream underlying the archive?  It also 
seems that doing so would ensure serialization / deserialization would 
be more consistent and self-sufficient, since neither process would 
depend on a (mutable) global locale setting.  At any rate, the 
serialization library works with certain window's codepages, but *not* 
with the utf-8 codepage (65001).  It would be nice to have the library 
use its own utf8_code_cvt facet to translate wide characters to 
multibyte.  If there is some work around I'm not aware of, I would 
appreciate any advice.  Thanks.
